I have a taylorcraft f-19 with the Continental O-200. I’ve been having some midrange issues when the oat is below 10*f. Today it was -4*f and with carb heat off it would run up to 2000 rpm then start cutting out, I’d then add carb heat and it would run very smooth up to wide open throttle. While cruising at 2400rpm it would run smooth without carb heat, then when decelerated I’d have to give carb heat to keep engine from stumbling. While landing I’d leave the carb heat on Incase I needed to make a go around and taking off I’d run up to WOT with carb heat then turn the heat off to get another 150rpm for max static of 2600 which is norma. My plane has a fresh overhaul with 100 hrs , good compression, mag drop is about 25rpm on each side, carb heat drop at 1800 is about 150rpm, oil temp after 1 hr is getting up to about 110 and I’m getting a rise of about 30 rpm with idle cutoff. My concern is if this is normal to need carb heat at a low cruise setting or if anyone has experienced similar symptoms. I’m hoping it’s normal so I don’t need to get my carb overhauled. Thanks. Adam
